THE GOOD
Having 2 bedrooms and 2 bathrooms is super convenient. This place could easily accommodate 4 people.
There's maid service twice a week, washer and dryer, plenty of towels.
The swimming pool was super refreshing (and mostly empty) during the heat of the day.
Hanging out in Kaoh San Road is fun for a couple of nights, and the proximity to a lot of the main temples is convenient.

THE BAD
The place is about a 12 minute walk from the Kaoh San Road area, which is a popular backpacker section of Bangkok. But in the relentless heat of Bangkok (average of 90 Fahrenheit in early September), you *may* occasionally want to hail a cab.
And here comes the first problem: the place is tricky to find, street signage in Bangkok is sparse around the area, and most taxi drivers don't know how to get to the building.
To make mattes worse, even drivers who know how to get there, have difficulty, because the streets leading to the building are SUPER narrow AND have really tight turns, that a lot of drivers don't even want to pick up or drop off near the building, opting instead to do so by the main road.
Another issue with the place is that Kaoh San road gets old after a couple of nights. It does have a variety of restaurants (mostly open door), and live music (super packed venues). But that's it. The proximity to the temples is nothing compared to the lack of things to do after hours. Taking a cab to other areas, such as Sukhumvit, where there are plenty of malls, movie theaters, restaurants, and night life, is fine, but coming back can be tricky, for the reasons listed above (and because drivers consider it "far").

SUMMARY
The place is fantastic, but the location is tricky.
I'd suggest only a short stay unless (2 nights tops)
